Lockheed Martin has released a new video showing one of its two S-97 Raider prototype attack helicopters strutting its aerial stuff. Based on the remarkably fast X2 technology demonstrator with its co-axial rotor and push propeller design, the Raider is being developed by Lockheed subsidiary Sikorsky as part of an independent bid to provide the US armed forces with their next generation of combat rotorcraft.
